Look up any domain WHOIS and registrar data that is publicly available
Authentication
ApiStacks uses API keys to authenticate requests. You can view and manage your API keys in the Dashboard.
Your API keys carry many privileges. To keep them from being abused, please do not share the keys on client-side code or Github etc. Keep them very secure.
All requests made to the API must contain the parameter api_key in each of your requests. API requests without authentication will fail.
All API requests must also be made over secure HTTPS. Requests made over plain HTTP may fail.
Endpoint
GET /getwhois
Parameters
api_key (required)
In your Request URL, provide the API Key found within your Dashboard
url (required)
The domain name that you want to retrieve registrar information from, e.g. http://abc.com
Premium Parameters
These parameters require a paid subscription to modify
response_type (optional)
Set to “JSON”, “XML”, or “YAML” depending what type of response you want from the API.

}Rate Limiting
Each subscription has its own rate limit. Your limit is based on your subscription plan (free or paid). If you exceed your limits, don’t worry. You can always upgrade or downgrade at any time.
When you reach a rate limit (both daily and monthly), the service will stop responding and return an HTTP 429 response status code. The error will contain the following JSON string body text.
{
"status": "fail",
"data": "",
"reason": "Usage limit reached. Please review/upgrade your account"
}
A reminder email will be sent to you when your API usage reaches 80% and 90% so that you can take immediate actions such as upgrading your plan in order to prevent your application using the API from being interrupted.
Error Codes
ApiStacks uses standard HTTP response codes to indicate the success or failure of an API request.
If the response code is not 200 Ok, it means the operation has failed. You can check the response for a field called ‘reason‘ that briefly explains what the error may be.
| Status Code | Reason |
|---|---|
| 400 | The request was not complete or malformed. Parameters may be missing |
| 401 | API key was not provided or was not valid |
| 403 | Usage limit was likely reached or the app was not enabled in the dashboard |
| 404 | API Endpoint does not exist |
| 405 | Method is not allowed (Only use GET) |
| 500 | An error occurred on our end |
